Kodi pali kusiyana kotani pakati pa HPMC ndi CMC?

HPMC (hydroxypypyl methylcellulose) ndi cmc (carboxymethyl cellulose) onse amagwiritsidwa ntchito cellulose, zomwe zimagwiritsidwa ntchito kwambiri mu chakudya, zomanga ndi minda ina.

1. Kapangidwe ka mankhwala ndi njira yokonzekera

Hpmc:
Kapangidwe ka mankhwala: hpmc ndi gawo lopanga polymer lomwe limapangidwa ndi cellulose yokhudza cellulose yokhala ndi ma propeln oxide ndi methyl chloride pambuyo pa mankhwala.

Chigawo chachikulucho ndi mphete ya glucose, yomwe imalumikizidwa ndi magulu a 1,4-β-β, ndipo magulu ena a hydroxyl amasinthidwa ndi methoxy (-Och₃) ndi hydroxypropyl (-ch₂chohyp₃).
Njira Yokonzekera: Choyamba, cellulose amathandizidwa ndi sodium hydroxide kukonza ma celloluse, kenako adachita ndi ma prowyl chloride ndi ma propy owuma kuti apeze HPMC.

CMC:
Kapangidwe ka mankhwala: CMC ndi cellulose yochokera ku cellulose yopangidwa ndi cellulose ndi chlorooceic asidi pansi pa milkiline.
Chigawo chachikulucho chimakhala mphete ya glucose, yolumikizidwa ndi magesi 1,4-β-β, ndipo magulu ena a hydroxyyl amasinthidwa ndi carboxymethyl (-ch₂cooh).
Njira Yokonzekera: Chuma chimagwira ndi sodium hydroxide kupanga ma celloluse, omwe kenako amayamwa acid acid, ndipo pamapeto pake satenga ma cmc.

2. Mankhwala akuthupi ndi mankhwala.

Kusungunuka:
HPMC: kusungunuka m'madzi ozizira ndi ena okhazikika, okakamizidwa m'madzi otentha. Njira yothetsera yokhazikika, gel yowoneka bwino imatha kupangidwa.
CMC: kusungunuka m'madzi ozizira ndi madzi otentha kuti apange yankho la colloidal colloidal.

Ma Ukuwoneka ndi Hhelogy:
HPMC: ili ndi mphamvu zambiri komanso kukhazikika kwa njira yothetsera matendawa, ndipo ali ndi pseudoplastic (shear dikirani) minyewa.
CMC: Ikuwoneka bwino kwambiri komanso mitundu yabwino yothetsera vuto la madzi, posonyeza thixotropy (kukulitsa pomwe matembenuzidwe, kupatulira mukasunthidwa) ndi pseudoplascity.

3. Zolemba

Hpmc:
Makampani Ogulitsa Chakudya: Monga thicker, sterubilera, emulsifier ndi filimu yomwe imagwiritsidwa ntchito yozizira, yamkaka, mafuta, ndi zina.
Makampani ogulitsa mankhwala: ogwiritsidwa ntchito ngati binder, kusanza ndikuwongolera kuti akonzekere piri.
Zipangizo zomanga: Zogwiritsidwa ntchito mu matope a simenti ndi gypsum kuti zithandizire kusungidwa kwamadzi komanso kugwirira ntchito.
Zodzikongoletsera ndi zinthu zosamalira payekha: zogwiritsidwa ntchito mu zotupa, zonona, shampoos ndi ma gels osakira, etc., kupereka kukula kwake komanso kukhazikika.

CMC:
Makampani ogulitsa zakudya: monga kukula, okhazikika ndi emulsifier, omwe amagwiritsidwa ntchito ku jamu, mafuta odzola, ayisikilimu ndi zakumwa.
Makampani ogulitsa mankhwala: ogwiritsidwa ntchito ngati binder, kunyalanyaza mapiritsi ndi filimu yomwe idayamba ndi makapisozi.
Makampani opanga mapepala: Ntchito ngati chonyowa othandizira othandizira ndi kuthinikizidwa pansi kuti apange mphamvu youma ndi kusindikiza kwa pepala.
Makampani opanga malemba: ogwiritsidwa ntchito ngati kuthinikizidwa wothandiziritsa ndi kumaliza wothandizira kusintha mphamvu ndi mabotolo a nsalu.
Makampani amakampani tsiku lililonse: ntchito ngati thicker ndi kusungunuka kwa zotsekemera, zopangira mano komanso khungu.

4. Kuteteza zachilengedwe ndi chitetezo chachilengedwe

Onse a HPMC ndi CMC ndi zida zopanda pake komanso zosasangalatsa zomwe sizingawonongeke ndi michere yaanthu mu thupi la munthu ndipo nthawi zambiri zimawonedwa zokhala ndi zakudya zotetezeka. Amasokonezeka mosavuta zachilengedwe ndipo ali ndi chopizikira chilengedwe.

5. Mtengo ndi msika

HPMC imagwiritsidwa ntchito kwambiri m'minda yomwe imafunikira kwambiri chifukwa cha kukonzekera kovuta, mtengo wokwera mtengo komanso mtengo wokwera.

Kupanga kwa masentimita kukhala kosavuta, mtengo wake ndi wotsika, mtengo wake umakhala wachuma, ndipo mtundu wa ntchito ndi wokulirapo.

Ngakhale HPMC ndi CMC ndi zonse zochokera pa cellulose, zimawonetsa mawonekedwe ndikugwiritsa ntchito chifukwa cha mitundu yawo yosiyanasiyana ya mankhwala, ma pyhnicosalmical katundu ndi magawo ogwiritsira ntchito. Kusankha kwa cellulose kuti mugwiritse ntchito nthawi zambiri kumadalira zofunikira pa ntchito ndi zomwe zimawaganizira zachuma.
